Cam 14,5

Cam 41028145 with an angle of 14.5°, made of aluminium, is a drive component of the Kranzle K 2195 TS/TST pressure washer pump. Mounted on the pump shaft, with a thrust bearing pack underneath it and the pump housing further down. The rotary motion of the motor turns the cam – its 14.5° angle generates the motion transferred through the bearing onto the pump pistons, converting shaft rotation into their reciprocating movement.

Application

The cam is mounted on the shaft of the K 2195 TS/TST pump. With each shaft rotation, the cam, set at a 14.5° angle, moves the pistons via the thrust bearing resting against its surface. The 14.5° angle determines piston stroke, and through that, the flow rate and pressure characteristics of the K 2195 TS/TST pump.

Replaced during cam assembly repair – after identifying wear on the cam surface, damage to the thrust bearing, or as part of a comprehensive pump drive overhaul.

Symptoms – when to replace

• Vibration or irregular pump rhythm not caused by piston seals or valves – suggesting wear of the cam working surface or thrust bearing.
• Visible signs of seizure, scoring or dull wear marks at the contact surface between the cam and the bearing.
• Axial play on the shaft with the cam fitted – wear of the component at the mounting position or in the bearing pack.
• Damage to the thrust bearing combined with signs of heating on the cam – bearing seizure frequently causes secondary damage to the cam surface.
• Corrosion or mechanical damage to the aluminium body – particularly at points of contact with the steel components of the bearing pack in the presence of moisture in the pump housing.

How to select the right part

Two parameters must match simultaneously: the 14.5° angle and the K 2195 TS/TST pump model. Identify by reference number 41028145 – the 41028 series numbering encodes the angle in the last digits (41028+145 = 14.5°), allowing cross-verification when the marking on the cam itself is illegible.

The K 2195 TS/TST model belongs to the Kranzle K-series line – different from the K 1050 TS, which has a separate pump design and accessories incompatible with 41028 series cams. Do not transfer parameters or part numbers from the K 1050 TS to the K 2195 TS/TST.

During disassembly, assess the condition of the bearing pack at the same time – both components work together and wear over a similar timeframe. The high 14.5° angle means a long piston stroke and high dynamic load on the thrust bearing with each rotation – bearing pack wear may progress faster than at smaller angles in this series.

Compatibility

Cam for the Kranzle K 2195 TS/TST pressure washer pump, angle 14.5°, aluminium body. Not a substitute for cams of other 41028 series models or for cams from other series (40460, 40473, 40523). Verify the exact compatibility range by reference number 41028145.

What is the difference between the K 2195 TS/TST and K 1050 TS models in terms of service parts – can replacements be used between these models?|The K 1050 TS and K 2195 TS/TST are different models with different pumps, different cam series and different accessories. The K 1050 TS uses DN10 connectors (M12×1), while most K-series models use the standard D12. Cams, bearing packs and seals between these models are not interchangeable. When servicing the K 2195 TS/TST, always identify parts by the reference numbers specific to this model – not by analogy with the K 1050 TS.

Does the high 14.5° angle mean faster wear of the cam and bearing compared to smaller angles in this series?|A larger cam angle at the same shaft speed means a longer piston stroke and higher dynamic load on the thrust bearing with each rotation. This theoretically results in higher stresses at the cam-to-bearing contact point compared to angles of 9.6° or 12°. In practice, operating conditions are decisive – regularity of oil changes, water quality and intensity of use. Do not shorten the preventive service interval solely because of the larger angle without other wear indicators.
